just drove the z and now it sounds like when you rev a radio controlled car.i last drove it a week ago and it was fine then..
it happens when i accelerate.if i stop,turn of the engine,then start it again its fine for a while,then i get this weired noise like an electric motor,with a slight hiss,not sure if the hiss was road noise as the road was damp.this is more alarming than the previous compressor sound i mentioned before...help:confused:
